well... don't you want the best for your son? i think he should live with both of you . every other week he can come live with you. like the first week he lives with you then the next week he lives with his dad ex......

Your son has reached the age where he needs his father and, if there is really no good reason for doing so, you shouldn't stop him, hard as this is for you. If you do try to stop him he will only resent you for it. He may find out that the grass isn't greener on the other side of the fence, in which case he will have concluded that for himself, which is better. I think you should let him find out.

Provided your ex isn't a violent man and your son is properly taken care of along with his education and your son is happy, there really isn't any good reason to stop him. I don't know whether this means he is having to change schools, has this all been well thought out with his best interests taken care of? Would he be moving far away from you?

If this goes ahead, do make sure that you settle the times when you will see your son. I wonder why you are against this, you don't go into detail about why you want to prevent your son from living with his father.

Without knowing the dynamic of both households, it's hard to tell what's the best choice.

I don't know what sort of visitation schedule you have going, or if the father lives near, but if it's at all feasible, let your son spend more time at his father's. It's possible that more male bonding is just what he needs at this age. If you oppose it, it's just going to make you out to be the mean parent, thus glamorizing his father to him all the more.

If his father doesn't live near you, then see if you can work something out for the summer months and school breaks. This will show that you are trying to be flexible and not disrupt his school schedule or personal life. Sometimes, all it takes is time spent with the other parent to realize that the custodial parent really was the better of the two. The grass is almost always greener on the other side of the fence with kids, and sometimes, all they need is a good dose of reality to set them straight.

why do you want to stop him? is his father a good parent? if not you should not agree to this. does his father have room for him? do you have other children? why does he want to live with his father?

these are questions you and your x need to answer. you might be able to stop it, but that may be up to a judge, if you and your x don't agree of whats best for the child.
